Problems solved by technology

[0004] Here, since the transformer is installed in the low-voltage area, high-voltage traces exist in the low-voltage area, resulting in a problem that the use area of ​​the low-voltage area is reduced, although it is necessary to ensure the space between the high-voltage area and the low-voltage area. Insulation, while insulation must be ensured between high and low voltage areas
Also, since one transformer can supply driving voltage corresponding to six phases, there is a problem that the power supply terminal is heated, for example

Abstract

An inverter gate board divided into a low-voltage region and a high-voltage region includes a plurality of drive circuits surface-mounted between the low-voltage region and the high-voltage region, each having a single main power source (SMPS) controller, and a plurality of transformers surface-mounted between the low-voltage region and the high-voltage region so as to supply a transformed voltage to each of the plurality of drive circuits, respectively.

Description

Technical field [0001] The present invention generally relates to an inverter grid, which is divided into a high voltage area and a low voltage area, and has a plurality of surface-mounted drive circuits between the high voltage area and the low voltage area to Drive multiple power modules individually. Background technique [0002] Generally speaking, the inverter is composed of a plurality of insulated-gate bipolar transistors (IGBT: Insulated-gate bipolar transistor) and supplies three-phase power to the motor. The IGBT of the inverter is operated by a gate drive circuit to supply a gate signal. In the prior art, if two motors are provided, two inverter gate boards are usually installed and operated so that a single main power source (SMPS: single main power source) supplies gate power to multiple IGBTs. [0003] The inverter grid has a low-voltage battery area and a high-voltage battery area. According to the prior art, a transformer is usually installed in the low-voltage a...
